[V8] V8 Digest V8 17" Tire Size

I have some 255/40-17s on 17x9 et35 rims and get no rub.
If you do the calculations, 255/40-17 is almost exactly the same diameter as
the stock size of 215/60-15.
However, as Jack states, the extra width of the rubber on the road can cause
all kinds of possibly unexpected sensations from hydroplaning to tramlining
to increased noise, etc. If you're front end components are compromised at
all, I'm talking about ball joints, tie rods ends, subframe bushings, etc.,
you will be very well aware of it with wider tires, even if you never felt
anything untoward before.
And weight has at least as big an effect on acceleration, if not more, than
diameter and its affect on final drive ratio. The combo I quoted above
weight 51+ pounds per tire and wheel and makes the car feel like a cattle
